The confined ground seismic damper is ground seismic dampening technology that softens the impact of earth movement and minimizes displacement of structures, by confining the ground with a continuous wall made of Implant Structures.
Liquefaction is controlled by enclosing the area surrounding the installation site with sheet piles, without having to apply treatment to structures such as facilities, railways, roads, etc. that cannot normally escape damage caused by liquefaction. A simple process that can be done in a shorter period of time and at low cost, and furthermore, can restore the ground to its original state by simply extracting sheet piles, so this method is a countermeasure for liquefaction while being friendly to the earth. This can be used as a countermeasure for liquefaction for all manner of existing infrastructure, whether it be above or below the ground.
With the synergistic effect of the Ring Method, which is used to control liquefaction by cylindrically enclosing the installation site of outdoor storage tanks such as those at a Petrochemistry complex, and the Lateral soil flow restraining pile method, which minimizes the lateral flow of surrounding ground, the entire facility is kept safe.
